Original Abstract

Non-stationary harmonic signals cannot be accu- rately represented by Fourier transform (FT). Fortunately, sev- eral methods for representing non-stationary harmonic signals exist including Fan-Chirp trasnform (FChT) or Harmonic trans- form (HT). This article is focused on the Harmonic transform and its computation. Estimation of slope of fundamental frequency change between analysed segments is essential for computation of the HT. The slope is estimated using several realisations of HT and comparing the spectral flatness. Optimisation of this procedure is presented in the article.
